REVOLVING FIRE-ARM.

BPECFICATION forming part of Letters Patent N o. 315,352, dated April 7,1885. Application filed Felrnary 5, 1885. (No model.)

To all whom itA may concern..-

Beit known that I, DEXTER SMITH, a citizen of the United States,residingl at Spring- "field, in the countyl of Hampden and State of Ioor-operating mechanism of such arms, the object being to provideimprovedl devices connected with and ,operating by the action of theframe and-barrel-joint for operatingthe shell-ejector.

In the drawings forming part of this speciication, Figure `1 is a sideelevation of a revolving v fire-arm embodying -my invention. Fig. 2 isaview of the barrel, partly broken away at the joint, the cylinder andejector, and a section of the frame, showing a portion of myimprovements applied thereto. Fig. 3 1illustrates detail parts of thejoint parts of the barrel and frame and the parts embodying myimprovements. v

Inthe drawings, D indicates that part of the pistol-frame extendingunder the cylinder b, and having the exterior cheek-pieces, mlm, of theframe and barret ioint. One of said cheekpieces has a curvedggroove, o,therein having an opening therefrom to the border of the cheek-piece atone end, as shown in .Fig. 3. A pin-hole, w, is made through the saidgrooved cheek-piece. A curved spring, a, is tted into the groove vin thecheekfp'iece m and secured there `by a screw through one end, as shownin Fie. l, said s rin@ a havin';v a in zi rot* D i 7 jecting from itsunder side, which passes through `the aforesaid pin-hole w and throughthe curved slot o in one of the interior joint parts, n, of the part hof the barrel, projecting beyond the inner face of said part n. A pin,z, `is placed in said part h of the barrel near the periphery of thecheek-piece m, to which spring a is attached, the end of said pin-havinga face inclining` toward the muzzle of the barrel.

Between the joint parts n n of the partl h of thev barrel is tted theejector-operating disk e, having the curved arm fthereon e is hung 0nthe joint-pin c, as shown in Eig.

The disk' 2. Said disk chas a-,curved groove, x, in one side thereof,which, when thezdisk is in operative position between said parts n,isdirectly under the curved slot o, through one of said parts. At oneend of the groove :c in

`disk e, and separated slightly therefrom, is

formed a shallow groove, mi.

When the abovedescribed joint parts of the frame 'and barrel and thespring a and disk e are assembled in operative positions, as in.

Fig. 1 the end of the arm i on'disk e is in position against theend ofthe ejectorstem d, the ejector then being' against the face of thecylinder b, and not in the position shown'in Fig. 2; and when the disk eand its armere in the position just stated, the end oi" pin Je? onspring c is in the curved groove m of disk c, at the end thereoffarthest fromthe arm Upon disconnecting the barrel from the'frame Y toswing the former to the position shownin Fig. 2 the end of the pin z* onspring afei-A lows the groove a: without turning disk e,.un.

til the ejector has swung high enough above the'frame tol let that andthe ejected shells move freely out, .and then the end of pin a strikesthe end of groove x near armi, swinging the disk c and carrying its armi against the end of the stem d, and driving the ejector out, as shownin Fig. 2. j l

In swingingthe parts m m upon the joint of the barrel part h, in whichis fixed the pinv 2, the end ofspringa is,when the ejector isthrown ontfar enough, carried onto the end of said pin, v

and is thereby, with pin z2, lifted up, drawingV said pin out of thegroove .r in diskc, freeing the latter and letting the usualretractingspring on stem d within the'cylinder draw back the ejector andswing disk e back to thepoint of starting. When disk e is swung back, asjust stated, that part of its face' beyond and in a line with the curvedslota: passes 11s-nder the end of pin z2 on spring a, and to somewhatfree the disk from the pressure'of spring a when it starts to rotatebackward and let the lejector return quickly against the end f thecylinder, the shallow groove mi is forme in the 'side of disk c. Theface ofthe end of pin z2 on spring a is slightly inclined ltoward itsrear side, so

that when it moves back from slot x to be the slight bridge betweenthese two slots. In swinging the barrel and frame into line againafterbperating the extractor the parts reassuine the position abovedescribed, ready to repeat the operation of the parts, as set forth.

What I claim as my invention isl. In a revolving' fire-arm, thecombination, with the frameand barrel joint parts and theeXt1actor4-steng fthereof, of a disk hung in the joint to ree'iproallyrotate on the joint-pin, said disk having an arm thereon engaging withthe extractor-stem, a sprin g attached to one of the cheek-pieces ofsaid joint having a pin thereon engaging with said disk, and means,substantially as deseribed,for disengaging said pin from the disk byrotating theA joint parts, substantially as set fort-11.

2. In a revolving fire-arm, thegrooved and perforated cheek-piece m,the4 joint part n, having a slot therein, the disk e, pivoted in' thejoint and having an armthereon and the groove x therein, the spring a,lying in the groove in 'said cheek-piece and-having a .pin

, ing an arm in the line o f movement of pin z,

and also having a'pin thereon engaging with said disk, substantially asset forth.

4. In combination With the barrel and frame joint of a revolvingfire-arm having the pin z .near saidjoint, the disk e, pivoted in saidjoint and having arm i and the grooves new', and the spring a on theframe, having an'arln in the path of movement of pin z, and having apin'y thereon engaging with said disk, substantially as set forth.

DEXTER SMITH.
